PAPER-IIANGERS TOOL.

I Application filed. September 30,1925. Serial No. 59,444.

Our invention relates to paper hangers trimming tools, and it has special reference to a tool, which is adapted to be used at corner edges in conjunction with a knife suitable for cutting wall paper, canvas and the like.

'Former tools of this kind are provided with a bevelled edge that is placed in or along the'corner edge of a molding, door frame, or the like, and an attempt made to tear the wallpaper along the edge, or a -knife is used to cut it alongside the said edge; this generally results in the point of the knife riding upon the face of the bevelled edge and becoming dull very quickly. Both are unsatisfactory in actual practice insomuch that only the most skilled workmen arecapable of handling them. Furthermorecorner edges are generally uneven, due

to particles of plaster protruding from the wall; alsoswellings are ever'present and which prevent "the entire length of the bevelled edge from making good contact with the wall surface at the said corner edge.

The principal object of our invention is to provide a trimming tool, which is adapted to serve as an eflicient guide under all work ing conditions forthe. edge of a cutting knife so that, after the wall paper or canvas has been pasted on the wall, a clean and straight out may be effected, as will hereinafter he explained, where it is necessary to trim the paper, especially at moldings, door frames, corners or any surfaces at an angle to the surface upon which the paper is placed.

Other objects are, ease and convenience in handling the tool so that even workmen of only moderate skill may be able to use the tool advantageously and thereby increase their speed and enhance the appearance of their work.

In the drawings, which illust ate the invention,

in his right hand. This view illustrates the manner of using the tool and a knife incon- ]unct1on therewith.

Our trimming tool, which is indicated by the numeral 4, comprises a fiat and straightblade 5, whichris provided with a straight, longitudinal edge 6, transversely rounded, as shown at 7, and a convexly curved edge 8, joining the longitudinal edge 6 at an acute angle, as is clearly shown inFig. 1,

for the purpose of allowing this end of the blade to offer no interference with projecting moldings in the operation of the device.

Furthermore, the pointofthe blade formed by the said two edges is adapted to be placed in the uppermost corne 1 where the trimming handle, as shown at 12, and embraces the blade and may be riveted thereto.

In actual practice, when a wall paper*13, or the like, is applied to. a wall 14: and it is desired to trim the edgebf the paper, as at a door-frame member'15, the trimming tool 4 is held in one hand of the operator, so that the longitudinal edge 6 bears in the corner edge upon the paper both on the surface of the wall let and on the surplus portion 16 that overlaps the corner edge of the doorframe member. The edgef6 being rounded, it is then easy for the operator to insert the point of a knife 17, held in his other hand, between the edge 6 and the surplus portion 16 of the paper at the top or the point where he desires to start the trimming of the paper. By this action, the edge 6 is sufliciently separated from the overlapping portion 16 to allow the knife to be held slantingly, as is shown in Fig. 3, and thus to reach into the extremity of the corner line 18. The operator thereafter simply lets the point of the knife 17 be guided by the straight and rounded edge 6 while he draws the knife along the corner line 18 formed by the junction of the wall 14 with the door-frame memher 15. This produces a clean cut regardless of the unevenness of the corner line and avoids the heretofore puckering or wrinkling of the paper when being trimmed by former devices. Vhen the knife has thus been drawn a. sufficient distance along the edge 6, the blade 5 is moved down still farther and the operation is repeated until the paper has been trimmed the whole length along the corner line 18.

Thus, it will be seen that it is necessary to have the edge 6 rounded, not bevelled or sharp, because, if the edge 6 were bevelled or sharp, the point of the knife 17 would ride thereon and be dulled immediately upon coming in contact therewith. Furthermore, with a bevelled edge applied at the corner l ne it is almost impossible to reach simultaneously into the said corner with the point of the knife. In my invention, because the edge 6 is rounded, the knife point and edge merely slides past the edge 6 and projects therefrom until it reaches the corner line 18, thus, the knife point does not contact with the blade 5 and hence can not be dulled thereby.

\Vhile in Fig. 3 the trimming tool 4 is shown as held in the left hand of an operator, and the knife 17 in his right hand, it is obvious, because of the equal rounding of the edge 6 on both sides of the blade 5, that the operator can hold the trimming tool in his right hand and the knife in his left, if he is left-handed, or if he, for the sake of convenience, prefers to manipulate the tool and the knife in this manner when the corner, where the paper is to be cut, is on his left side instead of his right.

hen it is so desired, the handle 10 maybe unscrewed from the blade 5, and the trimming tool is thus adapted to be conveniently packed in any suitable container for shipment or for carrying purposes.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while we have described the principle of operation, together with the device which we now consider to be the best embodiment thereof, we desire to have it understood that the device shown is merely illustrative and that such changes may be made, when desired, as fall within the scope of the appended claims.

Having thus described our invention, we claim as new and desire to secure by Letters Patent of the United States the following:

1. A paper hangers trimming tool adapted to be used in conjunction with a cutting knife, said trimming tool comprising a straight blade, provided with a straight, transversely rounded, longitudinal edge, the blade having a handle secured thereto opposite to said edge, and another edge joining the longitudinal edge at an acute angle thereto, as and for the purpose set forth.

2. A paper hangers trimming tool adapted to be used in conjunction with a cutting knife, said trimming tool comprising a straightblade, provided with a straight, transversely rounded, longitudinal edge, the blade having a handle secured thereto opposite to said edge, and a convexly curved edge joining the longitudinal edge at an acute angle thereto, as and for the purpose set forth.

In testimony whereof we affix our signatures.
